Yeah i was in dilemma too.
But i finally managed to get a super cheap hp, below rm100, for my main line.
Well, if you are going to use a weekly broadband, i would recommend you to get CBP, otherwise, the experience using other prepaid can be annoying (seeing that constant
error), and personally, i dont think it is worth my rm6 or rm20 since i would be frustrated, get annoyed and would be anger(purposely type anger not angry)..lol most of the time.
If you use internet on the go, most of the time, best is to get a cheap hp for your main line.
If you use internet mostly at home, and dont mind to fork out (rm200-rm300), then a usb modem seems the answer ( in long term, at least now you have a usb modem) or
buy a good cheap secondhand hp.
Or if you use internet mostly at home, and budget is a bit uptight, you are left with "keep-switching-your-sim card" option (provided that you dont mind missing calls at night, but maybe a No-No to ppl who constantly have important calls).
there's wifi all over the place i stay and study. I juz need the broadband for the once in a while out of town mission so getting a modem is not really necessary.
